CLIMATE CHANGE ECONOMICS AND POLICY
Reflect: In module 2 the economics of climate change and policy is introduced. In week 4, economic theory relating to externalities and public goods is introduced. It is argued that GHG emissions are an externality in the production and consumption of fossil fuels and that GHG mitigation has the characteristics of a public good. In week 5, BCA of climate change is introduced, including the potential risks and uncertainty. In week 6, the policies of mitigation and adaptation are introduced.
